CMUcam3: Open Source Vision Sensor

The CMUcam has been popular
with robot builders for a while. The third version of the CMU vision
sensor is out and should be even more popular becase CMU has open
sourced the code. The CMUcam3
is based
on the ARM7TDMI with code written in C and compiled using a standard GNU
gcc toolchain. The sensor provides 352x288 RGB CIF resolution, a frame
rate of 26 frames per second, and a basic image manipulation library
that includes image clipping, downsampling,thresholding, convolution
functions, color blobs, frame differencing, and historgram generation.
The CMUcam3 goes for about $240. For more technical details, see the
recently released technical report from the CMU Robotics Institute
titled, CMUcam3:
